Hi,

I want to send email using gmail SMTP. I got the following code from internet but I am getting following run-time error.

Kindly guide:

<

Exception in thread "main" java.lang.RuntimeException: javax.mail.NoSuchProviderException: smtp

        at SendMailTLS2.main(SendMailTLS2.java:46)

Caused by: javax.mail.NoSuchProviderException: smtp

        at javax.mail.Session.getService(Session.java:792)

        at javax.mail.Session.getTransport(Session.java:728)

        at javax.mail.Session.getTransport(Session.java:668)

        at javax.mail.Session.getTransport(Session.java:648)

        at javax.mail.Session.getTransport(Session.java:705)

        at javax.mail.Transport.send0(Transport.java:192)

        at javax.mail.Transport.send(Transport.java:124)

        at SendMailTLS2.main(SendMailTLS2.java:41)

>

My code is:

import java.util.Properties;

import javax.mail.Message;

import javax.mail.MessagingException;

import javax.mail.PasswordAuthentication;

import javax.mail.Session;

import javax.mail.Transport;

import javax.mail.internet.InternetAddress;

import javax.mail.internet.MimeMessage;

public class SendMailTLS2 {

public static void main(String[] args) {

final String username = "***@gmail.com";

final String password = "&&";

Properties props = new Properties();

props.put("mail.smtp.auth", "true");

props.put("mail.smtp.starttls.enable", "true");

props.put("mail.smtp.host", "smtp.gmail.com");

props.put("mail.smtp.port", "587");

Session session = Session.getInstance(props,

new javax.mail.Authenticator() {

protected PasswordAuthentication getPasswordAuthentication() {

return new PasswordAuthentication(username, password);

}

});

try {

Message message = new MimeMessage(session);

message.setFrom(new InternetAddress("**@gmail.com"));

message.setRecipients(Message.RecipientType.TO,

InternetAddress.parse("aa@yahoo.com"));

message.setSubject("Testing Subject");

message.setText("Dear Mail Crawler,"

+ "\n\n No spam to my email, please!");

Transport.send(message);

System.out.println("Done");

} catch (MessagingException e) {

throw new RuntimeException(e);

}

}

}

Some body please guide me.

Zulfi.

I think you wanted DESC, not DEPT.
DESC tablename;

Hi, @thatjeffsmith-oracle ,
Here is the picture from SQL Developer version 21.4.3.x,
Picklist is not showing with table alias 'a' as shown here.

That query to get the column list might take a half-second, be patient

hi @thatjeffsmith-oracle ,
No luck, i waited for a min but pick list not showing. I tried to change theme to dark as showing in your image, still no pick list pops up.

ask for it multiple times, if the query takes too long, we give up

Try Ctrl-Space.

Ctrl-Space is not working in Version 22.2.1.234

it brings up a different menu.

23.1.1 is latest and this is your example in 23.1.1
